That's not true everywhere in the USA. In quite many jurisdictions, a homeowner can do the work on his own house. If a violation already exists, I'm sure he is allowed to fix it. There are even a few areas where no requirement for licensing even exists. The NEC has no force of law unless the AHJ adopts it into law (a few use their own instead). A few locations have not adopted any electrical code (mostly rural).
